Abstract: Systems, methods, and computer readable media for detecting and mitigating address spoofing in messaging service transactions are disclosed. A messaging service firewall (MSF) separate from a short message service center (SMSC) receives a mobility management reply message (MMR) that is sent by a mobile location register element in response to an associated mobility management query (MMQ) and that includes a serving switch identifier. The MSF allocates a global title address (GTA) from a pool of GTAs and stores a correlation between the allocated GTA and the originating SMSC. The MSF replaces the serving switch identifier in the MMR with the allocated GTA and routes the modified MMR. The MSF then receives a messaging service message (MSM) that is addressed to the allocated GTA and that includes the purported originating SMSC. If the purported originating SMSC does not match the SMSC to which the GTA is correlated, the MSM is discarded.

Abstract: Methods, systems, and computer readable media for SMS forwarding are disclosed. A message service message routing information response message containing message service message routing information for a first destination may be received. The response message is modified to direct a mobile terminated message service message intended for the first destination to the message service message proxy. The mobile terminated message service message is received at the message service message proxy, which determines whether a message service message forwarding feature is enabled for the first destination. If a message service message forwarding feature is enabled for the first destination, it is determined whether the mobile terminated message service message is eligible for forwarding to a second destination. If the mobile terminated message service message is eligible for forwarding, signaling is initiated to forward the mobile terminated message service message to the second destination.

Abstract: A method is described for detecting an unauthorized service message in a communications network. The method comprising the steps of: receiving a signaling message associated with a supplementary service (SS) message and/or a unstructured supplementary service data (USSD) message from a first network node, the signaling message comprising identification information of the sender of the SS message and/or USSD message and first location information of the first network node; requesting second location information of the first network node from the a second network node serving the sender of the SS message and/or USSD message; and, comparing the first location information with the second location information in order to determine whether the SS message and/or USSD message is authorized or not.

Abstract: Methods, systems, and computer program products for delivery of SMS messages are disclosed. According to one method, first routing data for delivery of an SMS message to a mobile terminal is received at a network element. Second routing data is transmitted from the network element in response to receiving the first routing data. An SMS message having the second routing data is received at the network element. The second routing data is converted at the network element to the first routing data for delivery of the SMS message to a mobile terminal. The network element uses the first and second routing data to correlate a request for the first routing data with receipt of the SMS message. The network element compares an SMSC address in the request for the first routing data with an SMSC address in the SMS message to detect the presence of address spoofing.

Abstract: Methods, systems, and computer readable media for SMS forwarding are disclosed. One method includes performing steps at a message service message proxy separate from a short message service center and implemented on a computing platform including at least one processor. The steps include receiving a message service message routing information response message containing message service message routing information for a first destination. The response message is modified to direct a mobile terminated message service message intended for the first destination to the message service message proxy. The mobile terminated message service message is then received at the message service message proxy and the message service message proxy determines whether a message service message forwarding feature is enabled for the first destination.

Abstract: A method is described for extending a text message with content wherein the text message is sent by a mobile terminal via a Short Message Service Center (SMSC) of a communications system to a recipient and wherein the communications system further comprises a Content Service Center (CSC). The method comprises the steps of receiving at the CSC the text message originating from the SMSC; generating a content-extended text message by adding at least one piece of content to at least a part of the text message; and, sending the content-extended text message depending on the size of the content-extended text message in one or more mobile terminated short messages (MT/SM) to the recipient.

Abstract: A method and/or system delivers a short message service (SMS) message in an SMS-network comprising a network element to at least one mobile terminal which includes: receiving first routing data (imsi1) for delivery of said SMS-message to said mobile terminal at said network element transmitting second routing data (imsi2) from said network element in response to receiving said first routing data (imsi1); receiving at said network element said SMS-message comprising said second routing data (imsi2), and converting at said network element said second routing data (imsi2) to said first routing data (imsi1) for delivery of said SMS-message to said mobile terminal. The invention is particularly advantageous for identifying and/or preventing unauthorised delivery of SMS mobile terminated messages.
